Using Wavelength Splitting at the Remote Node to Mitigate Rayleigh Backscattering for Optical Wired and Wireless Access Networks
Fiber optics communications Optical communications
2015/6/10
We demonstrate an optical wired and wireless access network using wavelength-splitting (WS) at remote-node. A pair of CW carriers is generated from each laser source for wired and wireless application...
Wavelength Conversion Towards Rayleigh Backscattering Tolerant PONs via Four-Wave Mixing in SOA-based ONUs
Fiber optics communications Nonlinear optics four-wave mixing
2015/6/8
Wavelength shifting in PONs with downstream signal remodulation is presented,allowing upstream transmission over trees with 25km feeder and 1:32 split with penalties <2dB,originally Rayleigh backscatt...
Single Feeder Bidirectional WDM-PON with Enhanced Resilience to Rayleigh-Backscattering
Fiber optics Communications Fiber optics links subsystems
2015/6/8
We report a system demonstration of 6dB-enhanced tolerance to distributed reflections for WDM-PONs using commercial 1.25Gb/s SFP reflective transceivers. The scheme, based on 8B10B-coding and high-pas...
Effects of Rayleigh Backscattering in Long-Reach RSOA-Based WDM PON
Fiber optics links subsystems Semiconductor optical amplifiers
2015/6/8
We investigate the effects of Rayleigh backscattering in a long-reach RSOA-based WDM PON. The results show that the Rayleigh-induced penalty depends highly on the gain of the remote EDFA and the lengt...
Influence of Rayleigh Backscattering on the Performance of NOLM-Based Phase-Preserving Amplitude Limiters
Nonlinear optics fibers Phase modulation
2015/6/5
Design and fiber optimization in NOLM-type regenerators allow for a substantial decrease in excess noise originating from Rayleigh backscattering. Cascaded operation of up to 20 phase-preserving limit...
Reduction of Rayleigh Backscattering and Reflection Effects in WDM-PONs by Optical Frequency Dithering
Rayleigh Backscattering Reflection Effects WDM-PONs Optical Frequency Dithering
2015/8/6
The reduction of both Rayleigh backscattering and reflections in passive optical networks with remotely seeded network units by means of optical frequency dithering is demonstrated.
